Basic Toolbar not activating?

Hi,

Maybe someone can help me with my issue.
I want to use the basic editor, so I went to \ckeditor\_source\plugins\toolbar\plugin.js and changed line 513 below:

CKEDITOR.config.toolbar = 'Full';
to
CKEDITOR.config.toolbar = 'Basic';

and saved the file. However the editor is still showing the full toolbar even after several refresh, different browsers, etc. Can someone assist?

Thanks.
